My invention relates to improvements in paperifeeding machines, and more particularly to that class or type known as pile feeders used in connection with the feeding or delivery of sheets of paper to printing presses from a stack or pile of paper.

The primary object of my invention is the' provision of a generally improved machine of this class which will be exceedingly simple in construction, cheap of manufacture, and efficient in use.

A further object of the invention vis the provision of a machine of this class which maybe readily attached Vor used in connection with printing presses of varying forms,

. or types, as wellV as onewhich may bereadily adj usted for the feeding or delivery of sheets of varying forms and dimensions.

. A still further objectV is the provision of improved pile supporting and sheet feeding and A sheet separating mechanism together with improved sheet actuated tripper mechanism for causing said' sheet feeding and sheet separating mechanism to feed and separate the lowermost and superposed sheets held by the pile supporting means in coperative and properly timed relation to the gripping rolls and other parts of the press.

A still further object is the provision kof improved sheet feeding and sheet separating mechanismtogether with improved means for actuating the same with relation to the superposed pile or stack ofsheets to be fed.

lVith the above mentioned and other ends in v ieW, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings forming a part of this specifica-tion, Figure l, is a side elevation of the improved machine as it appears attached to the front or feed end of the press.
